Refrigeration System Monitoring with a Wireless Network

Challenge

Walk-in coolers can often have a lot of foot traffic causing the temperature to fluctuate as the door gets repeatedly opened. A temperature monitoring device is needed to ensure that a refrigerated storage room doesn't become too warm and potentially destroy the food that is located inside.

Solution

A resistance temperature detector senses the temperature of a walk-in cooler and sends the data to a SureCross FlexPower Node. The Node in turn sends that data to a Gateway, which issues an alarm to management if the temperature exceeds acceptable limits. The DX80 FlexPower Nodes have a IP67 rating for rugged environments and work well in the cold.
